Well, you could always use the tint screen command to make it black and white. Just adjust the grey setting. I'm sure you thought of that though, and I'll admit stuff doesn't always look great when you use tint screen.

If you have a program like GIMP or Photoshop you can use it to make a grayscale version of the tilesets. Using tint screen will turn the entire screen, including the player characters, black and white. I take it that you don't want that, and only want the tilesets black and white. I'm currently making some myself, though I have a lot of tiles to go through, and I haven't started on the RTP ones yet.

@Super Galaxy Convoy I did think of that but I don't have the proper programs to make the titles on grayscale, though I am getting photoshop elements with my new scanner so maybe ill just use that once I get the chance. Oh, did you mention you were making greyscale titles, I would love to see them once they are finished!
